An honest Irish suburban police sergeant in Melbourne, superstitious to the core, agrees to look after the drunken wife of an ex-member of the force who had been dismissed because of the sergeant's evidence years before. A faithful old servant, the wife's cleverness, the sergeant's honesty and superstitions, the suspicions of an over-sharp constable, and the cunning of the false husband who murders his wife for the insurance are included. The sergeant's loss of memory and the constable's spying nearly lead to a false conviction at the inquest. (PB)
